Th vessel Z is made of either an elastic or flexi ble material or with an elastic, pistonlike seal. After this vessel has been placed into the cylinder, the apparatus ,is filled with the '80 pressure fluid and then the plunger 6 and the threaded part a! are again fitted into the cylinder 'and the threaded part is screwe( down. In consequence of the contrary action of the spring a the packing material e. is thereby compressed and bulges out at the sides so theta perfectly tight joint is ob tained. Wheiu the. part (2 is screwed down still farther, the, resistance of the spring 0 is overcome and thence a great pressure is exerted on the press liquid. Thereby a high hydraulic pressure is produced in the machine, which is communicatedto the ma- Vessel Z, asthe material or has 95 an elastic seal.

The height of the pressure is read pressure gage 9. With delicate germs,

Incensequence of the pressure prevailing within the apparatus this plunger is shot up with a loud report and a part of the liquid will follow; The result is a sudden drop in the pressure in the cylinder and in the vessel Z. By such'sudden drop of the pressure even tough germs are killed;

When the arrangement is to be used for preservingor pickling hams, the cylinder a filled with brine after the hams or the like have been placed into it and then a sufmeans of the plunger -7) and the threaded part (Z. By this pressure the brine is quickly forced into the pores'of the ham and the latter is pickled withinashort. time.

With the constructional form of the arpressure impulses are to be exerted. The same with the afore described constructional form we here have a cylinder a to be filled with pressure liquid, in the lower part of which cylinder is placed the vessel Z with the material to be sterilized or preserved. The plunger b is, however, here arranged not only .over but also in the pressure liquid in the cylinder, so that the latter is divided thereby into two pressure chambers c and c of which the latter is connected with the pressure'gage g. The plunger 5 is not directly under action of the threaded 'part closing the top of the cylinder, but bears by a concentrically arranged rod a, bored through almost its entire length, and a cross piece 0 adjustably fitted to the threaded upper end of the rod on two studs p projecting upward from the threaded part cl. A. tight joint between the plunger and the threaded part and the Wall of the cylinder respectively is obtained by means of a packing a placed on the facing surfaces and by the disks {9, which rest against shoulders in the inner wall of the In the rod 11. a bolt-shaped small plunger g) is adjustably fitted by means of a screw spindle r and forms a tight joint therein. The cavity within the bored rod n communicates below by means of transverse When the vessel Z containing the material to be sterilized or 'the material to be preserved has been placed into the cylinder and its chambers 0 0 have been filled with the pressure liquid or the preserving liquid respectively,the screw spindle r is turned and there-' by the plunger bolt p is screwed into the cavity of the rod n which may, if desirable also be filled with the liquid. The pressure the liquid contained therein is transmitted through the transverse bores s to the liquid in the.

pressure is produced, which may be read 011' the pressure gage g. lVhen the required pressure has been reached, the cross piece 0 is turned away from the supporting stud 1?,

whereby it loses its support (see Fig. 3, dotand-dash lines). The pressure on the plunger b then suddenly drives the latter into the chamber 0 whereby the pressure on the liquid contained in this chamber is suddenly increased. Thence the pressure is transmitted to the material to besteri-lized or preserved. By these suddenpressure impulses all bacteria contained in the material to be sterilized, and even the toughest, are killed, orthe preserving medium is forced into the pores of the material to be preserved or sucked into them.

The third constructional form illustrated in Fig. 5 difi'ers from the first form hereinbefore described only in that the plunger 6 which passes with its upper reduced portion through the threaded part d is centrally bored through its Whole length, and that,

similar to the arrangement shown in Fig. 2,.

a bolt-shaped small plunger q can be moved forward into this here or 'its stufiing boxrespectively by means of a screw spindle 1'. The plunger 7) is threaded at the top of its reduced end and held by nuts 6 to the threaded part 05, so that the supporting spring as m Fig. 1 can be omitted. After the material to. be sterilized or preserved respectively has been introduced into the cylinder a and the plun er b with, the threaded part (1 has been fitted in position, the nut t is first tightened, so that the packing between the two parts is compressed and bulged out at the sides thereby producing a tight joint. Then the pressure liquid is filled through the longitudinal bore of the plunger into the cylinder a up to the rim, or

is refilled respectively, in case liquid had been previously contained therein. the stuifing gland u with the plunger q have been fitted the cap is tightened further whereby already a high pressure is produced. The final. highest pressure is produced'by driving in the plunger q by means of the screw spindle 1". By turning aside the lever 70 the pressure. may be again released, in the same manner as hereinbefore described. I
